A charismatic leader can turn a nation into a super power. A leader needs to be brave, farsighted and diplomatic to build his nation. Without a leader a nation is like a unguided mob who don't know what to do. So for economic development leadership is important. Just look at how a country like japan became so well developed even they are low in natural resources. Malaysia and Vietnam can be a great example of that to show how leadership can change a countries economy.
My country is another exam, the president is weak and have no good reasoning as a leader and it is affecting the country. The country is going backward instead of things to turn out good. Leadership means taking people along and if the leader doesn't have the strength it will draw the country backwards and the people will be affected. The great countries we see today I where they are because of good leadership. The kind of leaders a country has will determine if the country will move forward or not.
